I want to swap the x-axis and the y-axis and turn this graph into a horizontal graph
my python code
an_image = PIL.Image.open("static/img/t2.jpg")
gray_img = ImageOps.grayscale(an_image)
image_sequence = gray_img.getdata()
image_array = np.array(image_sequence)
with plt.style.context('dark_background'):
plt.plot(image_array[:1024], color='white' )
plt.savefig('static/img/his.png')
I'm not sure if that's what you want, but this will swap x-axis and y-axis of the original graph:
an_image = PIL.Image.open("static/img/t2.jpg")
gray_img = ImageOps.grayscale(an_image)
image_sequence = gray_img.getdata()
y = np.array(image_sequence)
with plt.style.context('dark_background'):
# Create the x-axis with the same size as y-axis
x = np.arange(0, 1024)
# Plot x-axis and y-axis in swapped positions
plt.plot(y[:1024], x, color='white')
plt.savefig('static/img/his.png')
If I want to move x-axis to the top What do I have to do?
Just add
plt.gca().xaxis.tick_top()
before saving the fig.
Full code:
an_image = PIL.Image.open("static/img/t2.jpg")
gray_img = ImageOps.grayscale(an_image)
image_sequence = gray_img.getdata()
y = np.array(image_sequence)
with plt.style.context('dark_background'):
x = np.arange(0, 1024)
plt.plot(y[:1024], x, color='white')
plt.gca().xaxis.tick_top()
plt.savefig('static/img/his.png')
